    A Common Genetic Origin for Early Farmers from Mediterranean Cardial and Central European LBK Cultures (2015)
    Oxford University Press
    Details
    Publication Date: 2015-11-20
    Description: The spread of farming out of the Balkans and into the rest of Europe followed two distinct routes: An initial expansion represented by the Impressa and Cardial traditions, which followed the Northern Mediterranean coastline; and another expansion represented by the LBK (Linearbandkeramik) tradition, which followed the Danube River into Central Europe. Although genomic data now exist from samples representing the second migration, such data have yet to be successfully generated from the initial Mediterranean migration. To address this, we generated the complete genome of a 7,400-year-old Cardial individual (CB13) from Cova Bonica in Vallirana (Barcelona), as well as partial nuclear data from five others excavated from different sites in Spain and Portugal. CB13 clusters with all previously sequenced early European farmers and modern-day Sardinians. Furthermore, our analyses suggest that both Cardial and LBK peoples derived from a common ancient population located in or around the Balkan Peninsula. The Iberian Cardial genome also carries a discernible hunter–gatherer genetic signature that likely was not acquired by admixture with local Iberian foragers. Our results indicate that retrieving ancient genomes from similarly warm Mediterranean environments such as the Near East is technically feasible.

    Determination of the Residual Anthracene Concentration in Cultures of Haloalkalitolerant Actinomycetes by Excitation Fluorescence, Emission Fluorescence, and Synchronous Fluorescence: Comparative Study (2016)
    Hindawi
    Details
    Publication Date: 2016-01-27
    Description: Polycyclic aromatic hydrocarbons (PAHs) are compounds that can be quantified by fluorescence due to their high quantum yield. Haloalkalitolerant bacteria tolerate wide concentration ranges of NaCl and pH. They are potentially useful in the PAHs bioremediation of saline environments. However, it is known that salinity of the sample affects fluorescence signal regardless of the method. The objective of this work was to carry out a comparative study based on the sensitivity, linearity, and detection limits of the excitation, emission, and synchronous fluorescence methods, during the quantification of the residual anthracene concentration from the following haloalkalitolerant actinomycetes cultures Kocuria rosea, Kocuria palustris, Microbacterium testaceum, and 4 strains of Nocardia farcinica, in order to establish the proper fluorescence method to study the PAHs biodegrading capacity of haloalkalitolerant actinobacteria. The study demonstrated statistical differences among the strains and among the fluorescence methods regarding the anthracene residual concentration. The results showed that excitation and emission fluorescence methods performed very similarly but sensitivity in excitation fluorescence is slightly higher. Synchronous fluorescence using  nm is not the most convenient method. Therefore we propose the excitation fluorescence as the fluorescence method to be used in the study of the PAHs biodegrading capacity of haloalkalitolerant actinomycetes.

    Essential role for Nix in autophagic maturation of erythroid cells (2008)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2008-05-06
    Description: Erythroid cells undergo enucleation and the removal of organelles during terminal differentiation. Although autophagy has been suggested to mediate the elimination of organelles for erythroid maturation, the molecular mechanisms underlying this process remain undefined. Here we report a role for a Bcl-2 family member, Nix (also called Bnip3L), in the regulation of erythroid maturation through mitochondrial autophagy. Nix(-/-) mice developed anaemia with reduced mature erythrocytes and compensatory expansion of erythroid precursors. Erythrocytes in the peripheral blood of Nix(-/-) mice exhibited mitochondrial retention and reduced lifespan in vivo. Although the clearance of ribosomes proceeded normally in the absence of Nix, the entry of mitochondria into autophagosomes for clearance was defective. Deficiency in Nix inhibited the loss of mitochondrial membrane potential (DeltaPsi(m)), and treatment with uncoupling chemicals or a BH3 mimetic induced the loss of DeltaPsi(m) and restored the sequestration of mitochondria into autophagosomes in Nix(-/-) erythroid cells. These results suggest that Nix-dependent loss of DeltaPsi(m) is important for targeting the mitochondria into autophagosomes for clearance during erythroid maturation, and interference with this function impairs erythroid maturation and results in anaemia. Our study may also provide insights into molecular mechanisms underlying mitochondrial quality control involving mitochondrial autophagy.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2570948/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2570948/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sandoval, Hector -- Thiagarajan, Perumal -- Dasgupta, Swapan K -- Schumacher, Armin -- Prchal, Josef T -- Chen, Min -- Wang, Jin -- F31 AI058932/AI/NIAID NIH HHS/ -- R01 AI056210/AI/NIAID NIH HHS/ -- R01 AI056210-05/AI/NIAID NIH HHS/ -- R01 AI074949/AI/NIAID NIH HHS/ -- R01 AI074949-01/AI/NIAID NIH HHS/ -- R01 GM087710/GM/NIGMS NIH HHS/ -- England -- Nature. 2008 Jul 10;454(7201):232-5. doi: 10.1038/nature07006.

    Dendritic cell apoptosis in the maintenance of immune tolerance (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-02-25
    Description: Apoptosis in the immune system is critical for maintaining self-tolerance and preventing autoimmunity. Nevertheless, inhibiting apoptosis in lymphocytes is not alone sufficient to break self-tolerance, suggesting the involvement of other cell types. We investigated whether apoptosis in dendritic cells (DCs) helps regulate self-tolerance by generating transgenic mice expressing the baculoviral caspase inhibitor, p35, in DCs (DC-p35). DC-p35 mice displayed defective DC apoptosis, resulting in their accumulation and, in turn, chronic lymphocyte activation and systemic autoimmune manifestations. The observation that a defect in DC apoptosis can independently lead to autoimmunity is consistent with a central role for these cells in maintaining immune self-tolerance.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, Min -- Wang, Yui-Hsi -- Wang, Yihong -- Huang, Li -- Sandoval, Hector -- Liu, Yong-Jun -- Wang, Jin -- New York, N.Y. -- Science. 2006 Feb 24;311(5764):1160-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Immunology, Baylor College of Medicine, Houston, TX 77030, USA. minc@bcm.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16497935" target="_blank"〉PubMed〈/a〉

    A mutation in EGF repeat-8 of Notch discriminates between Serrate/Jagged and Delta family ligands (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-12-01
    Description: Notch signaling affects many developmental and cellular processes and has been implicated in congenital disorders, stroke, and numerous cancers. The Notch receptor binds its ligands Delta and Serrate and is able to discriminate between them in different contexts. However, the specific domains in Notch responsible for this selectivity are poorly defined. Through genetic screens in Drosophila, we isolated a mutation, Notch(jigsaw), that affects Serrate- but not Delta-dependent signaling. Notch(jigsaw) carries a missense mutation in epidermal growth factor repeat-8 (EGFr-8) and is defective in Serrate binding. A homologous point mutation in mammalian Notch2 also exhibits defects in signaling of a mammalian Serrate homolog, Jagged1. Hence, an evolutionarily conserved valine in EGFr-8 is essential for ligand selectivity and provides a molecular handle to study numerous Notch-dependent signaling events.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3663443/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3663443/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yamamoto, Shinya -- Charng, Wu-Lin -- Rana, Nadia A -- Kakuda, Shinako -- Jaiswal, Manish -- Bayat, Vafa -- Xiong, Bo -- Zhang, Ke -- Sandoval, Hector -- David, Gabriela -- Wang, Hao -- Haltiwanger, Robert S -- Bellen, Hugo J -- 1RC4GM096355-01/GM/NIGMS NIH HHS/ -- 5K12GM084897/GM/NIGMS NIH HHS/ -- 5P30HD024064/HD/NICHD NIH HHS/ -- 5R01GM061126-12/GM/NIGMS NIH HHS/ -- 5R01GM067858/GM/NIGMS NIH HHS/ -- 5T32-HD055200/HD/NICHD NIH HHS/ -- K12 GM084897/GM/NIGMS NIH HHS/ -- P30 HD024064/HD/NICHD NIH HHS/ -- R01 GM061126/GM/NIGMS NIH HHS/ -- R01 GM067858/GM/NIGMS NIH HHS/ -- RC4 GM096355/GM/NIGMS NIH HHS/ -- T32 HD055200/HD/NICHD NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2012 Nov 30;338(6111):1229-32. doi: 10.1126/science.1228745.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Program in Developmental Biology, Baylor College of Medicine, Houston, TX 77030, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23197537" target="_blank"〉PubMed〈/a〉

    Notes: A sucrose-based simple medium (c-R5) is described on which protoplasts prepared from Bacillus subtilis are able to revert rapidly to bacillary forms. Transformations of B. subtilis protoplasts were performed using polyethylene glycol and various plasmid DNAs, followed by regeneration of the protoplasts on c-R5 medium. Regenerated bacteria were easily detectable on selective c-R5 medium after only 16 h of incubation at 37°C. This medium can be used for direct selection of various antibiotic-resistance markers. In addition, the c-R5 medium can be simplified to make it chemically defined, allowing the selection of prototrophs.

    Notes: Abstract A screening of plasmids in 25 nonpathogenic coryneform bacteria was carried out. 11 Strains showed at least one plasmid, ranging in size from 4.2 to 55 kb. These plasmids did not encode bacteriocin production or resistance to a number of antibiotics or to ions such as arsenite, mercury(II) and cobalt(II). A detailed study of plasmid pBL100 from Brevibacterium linens is presented. pBL100 has a size of 7.75 kb, and contains single sites for the endonucleases: Hin dIII; Pst I, Bgl II, Eco RI and Bam HI. B. linens is easily and efficiently transformed with vectors derived from pBL1 isolated from Brevibacterium lactofermentum.

    Notes: Fourteen species of non-pathogenic corynebacteria have been examined for the presence of DNases. Seven of the species were found to be DNase positive when assayed in Toluidine Blue-DNA-containing agar whereas only one, Corynebacterium callunae, could be detectable as DNase positive when the test was performed in DNA-methyl green-containing agar. Electrophoretic patterns obtained from sodium dodecyl sulfate-polyacrylamide gels containing DNA showed the presence of one or two bands of nucleolytic activity in two species of Brevibacterium and of several bands in C. callunae. Degradation of DNases by cellular proteases seem to occur in this species.
